In a sufficiently power-gamer magic-rich campaign, I'd play a golem which had become autonomous...
...except actually, it hadn't; my true PC is a gadgeteer-gnome lich who built a phylactery in the form of an iron golem, and who animates the golem rather than form a full (skeletal) humanoid body.
Alternately, what looks like an autonomous golem, is actually custom-designed iron armor, encasing the traditional skeletal-humanoid lich body.
Some actual races:
Phraints
